Wercker takes in $2.4 million to help developers test their code in the cloud

Wercker, a startup that aims to help developers build stable and maintainable code, brought in $2.4 million, bringing total funding to $3.2 million, said founder and CEO Micha Hernandez van Leuffen.

The startup, based in London and San Francisco, makes it easier for coders to practice continuous integration, a software engineering practice in which each change a developer makes to the codebase is constantly tested in the process so that software doesn’t break when it goes live.

The basic idea behind Wercker is that modern-day developers are building their applications across numerous cloud services and are under pressure to deploy their code to cloud service providers, like [company]Amazon[/company], fast, which can often lead to errors if proper testing is not done.

Wercker’s tool acts as the middleman between source-code hosting repositories like GitHub and cloud servers like Amazon Web Services. Each time a developer makes a change to his or her codebase in Git, Wercker can retrieve the code, builds a version of it inside a Linux Container (LXC) to isolate it, tests it for errors and then notifies the user if it either passed or failed.

Hernandez van Leuffen came up with Wercker’s underlying technology for his thesis project on containers and automatic resource provisioning at the University of San Francisco. With the popularity of [company]Docker[/company] and its take on container technology, Wercker is moving from Linux containers to Docker’s tech, which Hernandez van Leuffen sees as leading the momentum when it comes to application development.
